I want to teach you five of those things which deserve your greatest anxiety to acquire them: Have hope only in God. Be afraid of nothing but sins. If you do not know a thing never feel ashamed to admit ignorance. If you do not know a thing never hesitate or feel ashamed to learn it. Acquire patience and endurance because their relation with true faith is that of a head to a body, a body is of no use without a head, similarly true faith can be of no use without attributes of resignation, endurance and patience.

As I have said before, the ever more sophisticated weapons piling up in the arsenals of the wealthiest and the mightiest can kill the illiterate, the ill, the poor and the hungry, but they cannot kill ignorance, illness, poverty or hunger

Engineering is the art of modelling materials we do not wholly understand, into shapes we cannot precisely analyse so as to withstand forces we cannot properly assess, in such a way that the public has no reason to suspect the extent of our ignorance.

Dr AR Dykes

Wisdom and intellect is every man's friend, ignorance and illiteracy are his enemies.

Woe unto thee if after all thy profession thou shouldst be found under the power of ignorance, lost in formality, drowned in earthly-mindedness, envenomed with malice, exalted in an opinion of thine own righteousness, leavened with hypocrisy and carnal ends in God's service.

All religions, with their gods, their demigods, and their prophets, their messiahs and their saints, were created by the credulous fancy of men who had not attained the full development and full possession of their faculties. Consequently, the religious heaven is nothing but a mirage in which man, exalted by ignorance and faith, discovers his own image, but enlarged and reversed that is, divinized. The history of religion, of the birth, grandeur, and decline of the gods who have succeeded one another in human belief, is nothing, therefore, but the development of the collective intelligence and conscience of mankind.
